To all uihom 'it may concern: Be it known thatI, JOHN C'. BARBER, a-citizen of the United States, residing at Chicago, in the county of yCook and State 'of Illinois, have invented certain new and useful- Improvements in Antifriction vCenter- Bearings iorCars; and I dohereby declare thefollowing' to be a full, clear,` and exact' description of the invention, such as'will enable others skilled in the art to'which it appertains to make and use vthe same.

My present invention has -forits especial object to provide an 4improved anti-friction centerbearing for cars, and to this end'lit consists of thenoveldevices and 1 combinations of deviceshereinafter described and definedin theclaims. The invention` is illustrated inv the accompanying drawings wherein like charactersy indicate like parts throughout the severalviews.

Referring to the drawings: Figure lis a vertical section tak/en centrally through a center bearing designed in accordance with my invention. Fig. 2 is a plan view of the center bearing with the upperbearing member removed, and with some parts broken away, and Fig. 3 is a detail in end elevation showing one oi rollers being indicated by dotted lines.

The numeral 1 indicates the upper member, and the numeral 2, -the lower member of. the center bearing, the former of which is 'adapted to be bolted or otherwise rigidly secured to the body bolster of the ear, and the` latter of which isadapted to be bolted or otherwise rigidly secured to a truck bolster, which holsters are not` shown in the 'accompanying drawings. The upper bearing member 1 is formed with a depending hub 3 that works pivotally vwithin a-seat 4 formed in the 'center of the lower bearing member 2.A In practice the usual king bolt is adapted to be passed through the hub 3. As shown, the upper bearing member 1 is also formed near its outer portion with a depending annular thrust'flange 5 that surrounds a raised portion ofthe lower bearing member 2. The said thrust flange 5,

so-"called, also serves as a dust guard or shield.

Radially disposed conical bearing rgllers 6 are interposed between the bearing members 1 and 2, and are arranged to run upon conical bearing surfaces 7 and 8 formed respectively on the said bearing members. The upper bearing member 1 isprovidedwith an' annular shoulder 9 that engages the outer extremities of the bearing rollers 6, and the lowerbearing member 2 at theupper extremity of its central seat 4 is provided with outwardly extended lock lugs 11. The annular rib 10 ofthe said roller bearing member 2 is formed in its inner face with an annular groove 12. That portion oi the rib 10 that overlies the groove 12, and which operates as a lock flange, is formed with a plurality of notches 13.

The principal feature of this invention consists of a in one position of the ring 14 with respect to the bearmovements Iunder the pivotal movements of the bearling members with respect to each other, will, nevertheless, hold the said rollers interlocked to the said bearing member when the bearing members are sepa- Vin suchmanner that therollers, while free for the usual rated. In the construction illustrated, vthis roller l spacing device is inthe form of a ring 14 that is provided with a plurality of radially extended arms 15, which 'arms are oisuch channel shaped form in cross section, that they closely-engage the conical surfaces of the rollers between which lthey are interposed, and 'thus hold the said rollers properly` spaced apart, but .permit free rotation thereof.- The Vroller spacing device is shown as if stamped from sheet metal, but it may be either ofmalleable iron or of cast steel.

PreferablyA the lool; lugs 11 are unevenly spaced, and the spacing ring 14 at its inner edge is provided with corresponding spaced notches 16. Certain of the arms 15 are provided with outwardly extended locklugs 17, Vwhich in one position of the spacing ring are adapted to be passed through corresponding notches' the lock lugs 1l and 17 and notches 13 and ld is such and notches are turned into registration, and the said lugs and notches can be turned 'into registration only ing member 2.- The said spacing ring can be inter- 4locked to the said'bearing member entirely by the inner lock lugs or entirely by the outer lock lugs and cooperating lock iianges, but it is preferably interlocked to the said bearing member. both at its inner and outer portions.

that the spacing ring may be removed from or applied to the bearing member 2 only when the coperating lugs In assembling the parts of the center bearing, the i rollers are first applied to the bearing member 2 and then the spacing ring applied to the said bearing member and tothe rollers, and is then turned into 'suchposition that` under pivotal` movements of the center bearing incident to its service on a car, the coperating lock 'lugs and notches will not be brought into registration. 1f desired, a pin or other plug may be applied i to one of the notches 13 or 16 so as to thereby prevent separation of the roller spacing ringrom the lower bearing member even when the cooperating lugs and notches are turned into registration. The construction above described, while extremely simple and of small cost, is highly efficient for the purposes had in view. By the spacing ring interlocked to one of the bearing members, accidental separation or displacement of the rollers is prevented when the bearing members are separated either in the case of accident such as a wreck, or when 'the trucks are purposely removed from the car body. By reference, particularly to Fig. 3, it will be noted that the radial arms o the roller spacing and retaining ringl do not lcome into contact with either'tlie upper or lower members 2. 'ihe combinationwith upper and lower members of a center bearing', of conical rollers interposed between said members, and a roller retaining device in the form of a ring having radial arms, and Which yretaining device is intel-locked to and against separation from one of the said bearing members, but is free for traveling movements with said rollers, whereby said rollers are heid in position with respect to one of said bearing,r members, when the upper and lower bearingl members of ,the center bearing are separated, substantially as described. y

3. The combination with upper and lower members of a center bearing, of a roller spacingV and retaining device in th'e form of a ring having radial arms, and which spacing and retaining device is' provided with projections adapted to be interiocked to the lower bearing member by vertical and rotary movements, substantially as described.

4. The combination with upper and lower members of a center bearing, the latter having lock lugs 11, of conical bearing rollers interposed Abetween said members, and a spacing ringl 14' having radial arms l5 that engage said rollers, said ring and notches 1G which when turned into registration with said lock lugs 11, permit said ring to be Aapplied to or removed `fronrsaid lower bearing:r member, substantially as described.

`5. 1n a center hearing, the combination with an upper bearing member-1 having 'a depending hub Ii, of a lower kbearing member 2 formed with a center seat i i'or said hub 3, said bearing member 2 having lock lugs l11, and an annular rib 10 witlran-annniar groove 1:: and notches 13. conical bearing rollers 6 interposed between said bearingr members 1 and 2, and a ring 14 with radial roller spacing; and retaining arms 15, said ringhaving notches 1V. and certain-of said arms l15 having lock lugs 1T, substantially as and for the purposes set forth.

(i. The combination with upper und lower members ot" a center bearing, of a roller retaining device having.;y projet tions adapted to he interlocked to one of the said bearing;- members, by vertical and rotary movements, substantiall \v as described.
